AWeather is a real-time weather data viewer designed for weather enthusiasts. AWeather is not a weather widget/dockapp that displays a pre-computed forecast. It is designed to be an easy to use program that integrates a variety of meteorological data in a simple unified interface.
Currently, AWeather only displays data provided by the United States National Weather Service.

Grenouille is an online service for weather data. All data can be obtained in JSON and displayed on a map. The Web application is based on Flask and uses PostgreSQL. It can be deployed on Heroku. An example of a client for the Yocto-Meteo sensor is provided.

HOYRESPIRO is software developed for PEOPLE, a project promoting "smart cities" through rapid implementation, deployment, and uptake of innovative Internet-based services to face present challenges and improve future quality of life. HOYRESPIRO, developed for the pilot city of Bilbao, provides citizens with geo-referenced information about the air quality in and around the city, the pollen levels, the weather forecast, and weather information (updated every 10 minutes). It uses the existing network for environmental control of the city and the indicators developed with the data collected. The network consists of weather stations which measure atmospheric variables related to pollution and levels of pollen in the air.

Large Weather Icons depict a variety of weather conditions in all standard sizes from 16x16 to 512x512 pixels. Sunny and cloudy weather, mist, hail, fog, and snow weather icons are available with full online previews. Thanks to the huge maximum size of 512x512 pixels, Large Weather Icons are ideal for all types of software applications, Web sites, and presentations. Large Weather Icons are also available in Adobe Illustrator vector format.

OwfsWeather is a package that scans and logs weather data from various One-Wire weather sensors. It uses OWFS, the One Wire File System, to communicate with the sensors. It currently supports logging of weather data to Weather Underground, a CSV file, and to an RRD database. Current hardware supported is the WSI-601 weather station from AAG, a DS1820 temperature sensor, and the humidity and barometric pressure modules from Hobby Boards.

WDB is a weather data storage system for storage
of weather and water observations, forecasts,
analysis fields, and models. The system should be
compatible with the meteorological standards BUFR
and GRIB (version 1 and 2). In addition to generic
loading programs, WDB also features a flexible
retrieval interface for retrieving weather data in
time series or entire fields. WDB is built using
PostgreSQL extended with PostGIS.
